E-Prime® Extensions for EyeLink by Psychology Software Tools
E-Prime Extensions for EyeLink is available for E-Prime 3.0 users. While EyeLink users have always had the ability to access all versions of E-Prime through in-line scripts, PST’s official extension enables direct access to all EyeLink eye-trackers using dedicated E-Prime Objects and provides a rich and effortless integration with EyeLink Data Viewer. The E-Prime Extensions for EyeLink includes an EyeLink Toolbox with all necessary package calls to integrate EyeLink communication within an E-Prime 3.0 experiment, and includes PST software support.
The E-Prime extension for EyeLink provides a more streamlined way for users to:
- Calibrate, validate, and start and stop recording
- Use custom animated calibration targets (e.g., for infant tracking)
- Create interactive, gaze-contingent experiments
- Access EyeLink online events in E-Prime to detect saccades, fixations, and blinks
- Provide online E-Prime stimulus feedback to experimenter
- Use drag and drop pre-set EyeLink package calls for faster design
- Synchronize with external devices (e.g., EEG, fMRI, MEG, etc.)
Further, the new extension facilitates extensive EyeLink Data Viewer Integration:
- Automatically replay and visualize gaze data overlaid on E-Prime stimuli in Data Viewer
- Present video stimuli with full Data Viewer playback support
- Mark experimental events with millisecond precision
